Any easy way to modify DVFS tables ? Or perhaps set a set frequency for testing purposes.
I'd like to test out each frequency point (and do some undervolting) to see how power consumption responds. This used to be doable with a single command, not sure if it's possible now on newer kernel.
Thanks

Guys, you're going at this all wrong. For desktop use and 20$ best bet for a good experience is a used Dell, HP with a Core2 Duo type cpu. These are plentiful, since businesses get rid of them and you can easily pick one up for 20$ or less if you shop around.
It's going to give you much better desktop experience with common apps and OS than any A7 or A53 based SBC (these CPUs are muuuch slower than Core2). If you can spring extra $$$ for a few more gigs of ram (these typically come with either 2 or 4GB of ram) and a 60GB SSD (18$ from aliexpress) you can get a fluid desktop experience for peanuts.

So i've installed a bigger battery on my cheap A33 tablet. Previously it had a 1700mAh battery (rated for 3000mAh actually) for a 2x1700mAh setup. It works fine and actually works for longer, but the battery percentage is not correct anymore, since it now drops to 5% and stays there for some time until it completely discharges. Does need a special calibration (pmic is AXP223) or will a simple charge/discharge calibrate things ?

Even if they get h264 decoding working, its going to be a huge win for allwinner community.
Having a working h265 isn't really all that useful to be honest, since the common chips (H3,H5 etc) only support 8 bit decoding, while most media i came across is encoded for 10 bit.
h264 media on the other hand is still widely available, so having mainline support would be awesome. Now if someone would get this working under chrome or firefox, that would be a different ballgame
